We report the case of a 21-year-old woman who was referred after a severe compressive blunt trauma in the context of job injury. Myocardial contusion is a common injury; however, rupture of the ventricular septum after blunt chest trauma is a rare event. Echocardiography revealed a large ventricular septal rupture with two small ventricular septal defects. The patient was a candidate for surgical repair after early conservative management. We discuss about the prevalence and management of this rare traumatic complication.
